We've talked about the benefits of meditation a number of times before and recommended how anyone can get started. The process is really simple, but perhaps deceptively so. Meditation is mental training that isn't necessarily easy or even pleasant sometimes.

In a great post on Reddit, a user named wouldbebuddhist clearly describes the meditative process and why it's not easy when you first start meditating:

Every time you go back to the breath, you train or teach yourself even, to take the opposite of the path of least resistance. This is coupled with the fact that half the time when you meditate, your mind says, "I'm tired. Stop concentrating on the breath and just kick back and let a guided meditation do most of the work." But every time this comes up you learn to drop it by returning to the breath and not listening to the thought no matter how loud and powerful it can get.

After doing this hour after hour, you gain a skill. One day you realize that you don't have to be sitting on a cushion to use this skill. I can't really explain how it's done, but it's just something you learn from continually focusing, coming back to, and holding your attention on the breath. It's like if you ever do a lot of push-ups, eventually you will realize, "I can flex my pecs." You couldn't flex them before, and you don't really know how you learned to do it, but now you can just do it.

In other words, meditation takes work, but it becomes a skill you learn. If you're struggling while learning to meditate, don't worry—that's normal. On the other hand, if all you're feeling is relaxed while meditating, consider trying to focus a bit more during your practice.
